Major U.S. equity index futures tumbled during Monday’s pre-market session as heightened geopolitical tensions in the Middle East converged with increasingly hawkish Federal Reserve policy signals, shaking investor sentiment on the month’s final trading day.
Futures tied to the Dow Jones Industrial Average slipped 85 points, representing a 0.2% decline. Both S&P 500 and Nasdaq-100 futures similarly retreated 0.2% during early morning trading.

Crude Prices Jump Following Military Action Against Iran
American military forces conducted strikes targeting two Iranian rocket launching facilities located on Larak Island within the strategically vital Strait of Hormuz over the weekend. Tehran retaliated with attacks on U.S. military positions in Jordan and asserted responsibility for striking a commercial tanker in regional waters.
President Trump announced via social media that Iran’s primary oil export facility on Kharg Island was being “blown to smithereens,” although no official military sources have verified this assertion.
Brent crude advanced 2.3% to reach $90.17 per barrel. West Texas Intermediate gained 2.3% to settle at $85.32. Given that the Strait of Hormuz serves as a critical global energy transportation corridor, any potential disruptions typically trigger swift market reactions.
Rate Hike Expectations Soar Following Warsh Remarks
Federal Reserve Chair Kevin Warsh delivered remarks at the annual Jackson Hole symposium last Friday, indicating that market participants may be underestimating persistent inflation threats. His statements dampened expectations for monetary easing while elevating the likelihood of additional tightening.
Financial markets reacted immediately. The implied probability of a September interest rate increase jumped from approximately 40% one week earlier to between 57-60% by Monday’s opening, based on CME FedWatch tool data.
Barclays analysts revised their forecast to anticipate 25 basis point rate increases at both the September and December Federal Open Market Committee meetings. JPMorgan’s lead U.S. economist characterized the September gathering as “live” while maintaining an expectation for the initial hike to occur in December.
Two-year Treasury note yields stabilized at 4.34% following a sharp 12 basis point surge on Friday. Japan’s equivalent 2-year government bond yield touched a 31-year peak. Germany’s 2-year yield climbed to levels not witnessed since July 2024.
Elevated interest rate projections typically weigh on equity valuations, particularly impacting growth-oriented and technology sector stocks, which accounts for Monday’s early session weakness.
Notwithstanding Monday’s retreat, August has delivered positive performance overall. The Dow has climbed 2% during the month and appears positioned for a fifth consecutive monthly advance. The S&P 500 has appreciated nearly 3% while the Nasdaq has registered approximately 4% gains.
Critical employment data releases are scheduled for this week, including Tuesday’s JOLTS Job Openings report and Friday’s comprehensive U.S. Employment Report. Quarterly earnings announcements from Broadcom and Dell Technologies will also draw attention as investors assess ongoing artificial intelligence infrastructure investment trends.
Gold declined 0.3% to $4,437 per ounce but maintains approximately 10% gains for August.
